求翻译:The try block contains the guarded code that may cause the exception. The block is executed until an exception is thrown or it is completed successfully. For example, the following attempt to cast a null object raises the NullReferenceException exception. (See Fig.3.3-1 NullReferenceException exception)是什么意思?

try块包含了保护代码,可能导致异常。

Try 块包含可能导致异常的保护的代码。块一直执行到引发异常或成功完成为止。例如,以下的尝试将 null 对象强制转换引发举出异常。(见 Fig.3.3 1 举出例外)
